AApplication led January 28, 1921. Serial No. 440,683.

To @ZZ whom t may concern:

Be it known that F RANK BERMAN, a citizen of the United States, residing at Oregon, in the county of Dane and State of iilisconsin, have invented a new and useful Attachment for Hospital-Beds, of which the following is zkspecitication.

This invention relates to beds for invalids or hospital use.

An object of the invention is to provide a mounting tor the bed spring which is in the it'orm of an attachment to a bed and which may be applied to ordinary hospital beds without changing the construction of the latter.

Another object is to provide aV bed spring mounting which allows tilting of the spring about a horizontal axis longitudinally oi' the bed and also tree rotation of said spring about a vertical axis.

A still further object is to provide a bed spring support wherein the spring may be tiited to a desired extent and maintained indefinitely in that position.

Another object is to provide a bed attachment in which bed clothing will not catch so as to be torn.

Other generai objects are to provide an improved invalid bed which is sanitary, which permits the use of the bed for operations it desired, which is easily manipulated by the nurse or other attendant, and which makes the patient more at ease and more comfortable than most hospital beds. I

The invention will be best understood from a consideration of the following de tailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not coniined to any strict conformity with the showing in the drawing, but may be changed and modified so long as such changes and modiiications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 1 is a plan view of the improved bed, showing in dottedl lines an alternate position of the bed spring.

Fig. 2 is a vertical longitudinal section of the same.

Fig. 3 is a vertical cross section of the same.

Fig. 4 is a detail view of the means for bracket 12L as will now be described.

`effecting adjustment of the tilt of the bed springs.

The numeral 10 designates the end fra-mes of a bed, and 11 indicates the side rails thereof. The bedstead properv being of ordinary construction needs no description. Secured at opposite points on the side rails are two brackets 12 and 12a, any convenient means being employed to holdthem to the side rails. The two brackets depend vertically trom the rails 11. At the lowermost points of the brackets braces 13 are connected which are also secured to the rails 11 near the extremities thereof.

The brackets provide supports i'for a cross rod 14, said cross rod passing through perforations in the two brackets and being rotatable in said perforations. Means suchv as collars or cotter pins are employed to prevent longitudinil movement of the rod 14. For an intermediate portion of its length the rod 14 isiattened out or squared as indicated at 15. secured the lower plate 16 of a turntable. The plate 16 is circular and has a series or' arms 20 secured to the under side thereof and projecting above its upper surface. An upper circular plate 17 is rotatable about a bolt 18 joining the plates 16 and 17 to the rod section 15. Rollers 21 are carried by the upstanding arms 20 and the upper plate 17 rides under the rollers 2l. A coil spring 19 is uinterposed between the upper end ot' the bolt 18 and the Lipper plate 17 whereby the two plates are pressed together.

A plurality of bars 22 is secured to the upper plate 17. These bars, as the drawing shows, spread outwardly as well as up-A wardly and together provide a support Jfor the bed spring 23. The upper ends of the arms 22 are suitably shaped to receive and seat the frame ofthe bed spring whereby the latter may be secured to the arms 22.

By means of the,v described construction, it will be clear that the bed spring 28 may be tilted aboutI a horizontal axis, c', c., the axis of the rod 14, and it may also be rotated about the bolt 18 asa pivotal axis. Means for maintaining the bed spring in any desired tilted position is associated with the The rod 14 near the end which passes through bracket 12n carriesl a notched arcuate rack 24. A pawl 25 is pivotally mounted on the bracket 12a at one end and has a suticient To this portion of the rod is length to extend beyond the other end of said bracket. This pawl is L-shaped in cross section so that one flange thereof may depend vertically to partly house the rack 24. Thus the bed clothing is protected from the teeth of the rack. rIhe pawl 25 has a tooth 26 for engagement with one of the rack teeth. Obviously, when the pawl is in engagement with the rack teeth, tilting of the bed springs may not be effected. When the pawl is lifted out ot engagement, free tilting of the bed springs is allowed. However, the swinging of the bed spring to a position crosswise of the bed, as shown in Fig. l, may be done at any time without manipulating the pawl. rEhe spring 28 holds the pawl normally in engaging position while a handle 27 is provided at the end of the pawl projecting somewhat outwardly so that the attendant may lift the pawl easily and adjust the bed spring as desired.

What is claimed is l. In a bed, the combination of brackets secured to and depending from the side rails of the bedstead, a transverse rod journaled in said brackets, a turntable mounted upon the rod and supported below said side rails, a bed-spring mounted on the turntable and rotatable therewith, said bed-spring being supported above said side rails and thereby adapted to be tilted between and rotated above the side rails.

2. In a bed, the combination ot brackets secured to the side rails of the bedstead, a transverse rod journaled in said brackets, a bed spring mounted on said rod so as to be tilted when said rod is turned on its axis, and a turntable comprising a part of the bed spring mounting whereby the spring may be rotated and placed transversely of the bed, either side edge ot the spring being adapted to be supported on the rails of the bed when the spring is tilted in transverse position.

3. In a bed, the combination of brackets secured to and depending from the side rails of the bedstead, a transverse rod journaled in said brackets, a plate rigidly secured to said rod, a second plate held above the rigid plate and rotatable relative thereto, bars connected to the upper plate and rising up wardly and outwardly, and a bed spring supported upon the extremities of said bars above the side rails, said plates and transverse rod being supported below the horizontal level of the side rails.

4L. In a bed, the combination of brackets secured to the side rails of the bedstead, a transverse rod journaled in said brackets, a plate rigidly secured to said rod, a second plate supported upon the rigid plate and connected thereto s0 as to be rotatable there on, means compressing the central portions or' the upper and lower plateslagainst each other, a plurality of arms secured to the lower plate and rising above the upper plate, rollers carried upon said arms and bearing against the upper tace of the upper plate, bars connected to the upper plate and rising upwardly and outwardly, and a bed spring supported upon the extremities of said bars.

5. In a bed, the combination of brackets secured to the side rails of the bedstead, a transverse rod journaled in said brackets, an arcuate rack tast to the rod, a pawl pivoted on one of the brackets and engageable with the teeth of the rack, and a handle project* ing outwardly for lifting the pawl, said pawl forming a housing for the rack.

6. In a bed, the combination of brackets secured to the side rails of the bedstead, a transverse rod journaled in said brackets, an arcuate rack tast to the rod, a pawl pivoted on one of the brackets and engageable with the teeth ot the rack, said pawl being angular in cross section so as to house the upper portion of the rack and in conjunction with the bracket toA protect the bed clothing from the teeth et the rack.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature.

FRANK BERMAN.
